Configuring IGMP Snooping Multicast SSM Mapping

By configuring SSM mapping, you can set up one-to-one mappings between multicast groups and multicast sources.

SSM mapping applies to a VSI only when the IGMP snooping version running in the VSI is V3.

Run system-view
The system view is displayed.
Run vsi vsi-name
The VSI view is displayed.
Run igmp-snooping version 3
The IGMP snooping version is set to V3.

The default IGMP snooping version is V2, but this version does not support SSM mapping.
Run igmp-snooping ssm-mapping enable
SSM mapping is enabled in the VSI.

By default, SSM mapping is disabled.
Run igmp-snooping ssm-mapping ip-group-address { ip-group-mask | mask-length } ip-source-address
The mapping between a multicast group address and a multicast source is configured.
